[akshay-gupta7]

Why does this PR exist?

Closes #3650

What does this pull request do?

This pull request fixes the base API URL configuration for GitHub Enterprise. Previously, the plugin was using the default GitHub API URL, which caused issues when connecting to GitHub Enterprise instances that require a custom API base URL. With this update, the plugin correctly utilizes the enterprise-specific API endpoint, ensuring compatibility and proper communication with GitHub Enterprise servers.

Testing this change

• Verified against both public GitHub and GitHub Enterprise instances.
• Ensured that API requests route through the correct endpoints.
